four times a number increased by 12
write equation
Answer (2)
Let the unknown number be x."Four times a number" → 4 × x → 4x"Increased by 12" → add 12 → 4x + 12Equation4x + 12If there is a condition like "equals 28," you can complete it4x + 12 = 28 → solve for x:4x = 16 → x = 4
4f + 12We're asked to write the following expression:⇒ [tex]\textsf{four times a number increased by 12}[/tex]Step 1: Let our number be f.Or, in other words, choose "f" to represent your number in this expression. Instead of writing "the number", we use a letter to represent that. Let it be f.Step 2: Write "four times a number".Or, in other words, multiply f by 4.⇒ [tex]\sf 4*f=4f[/tex]Step 3: Increase 4f by 12.Or, in other words, add 12 to it.
